Abstract: This paper proposes and demonstrates an arbitrarily tunable multi-frequency pulse modulation scheme based on an active fiber loop, which effectively suppresses the interference fading effect ...

Abstract: Due to the wide applications of DPWM (Digital Pulse Width Modulation) /DPFM (Digital Pulse Frequency Modulation) in the industry, a 4-bit Dual Mode (PWM/PFM) Digital Pulse Modulation (DMDPM) ...
